Which musical tempo is defined as fairly quick and slightly slower than allegro?

The correct answer is that andantino is a tempo that is defined as fairly quick, slightly slower than allegro. In the context of tempo markings, allegro indicates a fast, lively pace, while andantino suggests a tempo that is brisk but not as fast as allegro, making it a moderate pace that can often feel light-hearted and joyful. This is why andantino is recognized as the correct term for this speed.

In contrast, lento refers to a slow tempo, moderato indicates a moderate speed, and allegretto, while it suggests a light and moderately fast tempo, is still faster than andantino. Thus, andantino accurately fits the description of being quick but not as fast as allegro.
